12 Claims.

This invention relates to devices for delivering paper to printing presses and has for its object to provide a new and improved device of this description. The invention has as a further object to provide a device for delivering paper to printing presses wherein the delivery of the paper is changed from an expiring roll to a new roll without stopping the press, and wherein there is provided means for severing the web of the expiring roll after it has been connected with the new roll. The invention has as a further object to provide an automatic severing device for high speed paper delivering devices. The invention has other objects which are more particularly pointed out in the accompanying description.

Like numerals refer to like parts throughout the several figures.

Referring now to the drawings wherein I have illustrated one form of the device embodying the invention, I have illustrated a construction where there is a roll supporting device having a shaft I carrying the roll supporting arms 2 between which are supported the rolls of paper 3, 4 and 5. The shaft is mounted upon suitable supports ,6 and I and is rotated by means of a motor 8 which is operatively connected with the shaft I, preferably by means of a worm and worm gear. A series of endless belts 9 each pass around a plurality of direction changing devices I0, Il, I2, I3 and I4. The shaft I5 in which the direction changing device I2 is mounted is driven in any suitable manner,l as by means of the driving shaft I6 and gears I1 and I8. The direction changing device I4 is movably mounted and is weighted so that it automatically moves as the diameter of taken on une 2-2 of 1932, Serial No. 831,181

the expiring roll decreases so as to keep the belts in proper engagement with the rolls.

When the roll which is delivering paper to the press has about expired the roll support is moved so as to bring the web of the new roll, as for 5 example the roll. 4, into contact with the web I9 of the expiring roll 3. The web of the new roll 4 is provided with adhesive material and the movement of the roll support moves the roll 4 so that the web thereof containing adhesive material is 10 pressed by the pressure device 2li against the web I9 of the expiring roll so that the two Webs are connected together. When the two webs are connected together the web of the expiring roll is severed and the delivery of the material conl5 tinued from the new roll.

In this construction, when the web I9 of the expiring roll is connected to the web 2l of the new roll, the two webs move along together toward the press. The web of the paper being de- 20 livered to the press passes between a suitable light source and a photo-electric cell unit. Since said web is partially transparent, there will `be a certain amount of light pass through it into the photo-electric cell unit, and this is arranged to 25 maintain an open circuit on this amount of light passing through the single web. When the web of the new roll, which has been connected to the web of the expiring roll, reaches this light-source, the amount of light passing through the double 30 web is reduced and the photo-electric device now actsI automatically to start the operation Yof the web severing mechanism. f

In the drawings I have illustrated one form of light source 22 on one side of the web I9, and 35 the photo-electric device 23 on the other side thereof. The light source 22 is connected by conductors 24 to the conductors 25 which lead to the source of supply. The photo-electric device 23 is connected by conductors 26 with the photoo electric relay and amplifier 21, which in turn is also connected to the conductors 25 leading to the source of supply. The photo-electric relay and amplifier 21 is connected by conductors 28 with the release magnet or solenoid 29 which has 45 its core connected to the lever 38 pivoted at 3|, the end 32 of which acts as a pawl for the cam 33 on the shaft 34. A spring 35 normally holds the cam in its holding or locking position.` i The severing device 36 is connected by armsf3lwithv5o the shaft 34 and is held in its operative vpositionv by the pawl 32.

In Figs. 5 and 6 I have shown the cam v33 separated from the arms 31 for purposes of clear--y ness, but it will be understood that the cam/33 55 `expiring roll.

and the arms 31 are on the lsame shaft 34. The shaft 34 ,also hs a segmental'gear 33 thereon which is engaged by a segmental gear 3,9 on the shaft 43. There is preferably a segmental gear- 33 and'33 at each end ofthe shafts 34 and". Connected with the shaft 43 are arms 4lfto which are pivoted rods amounted in swiveled bearings 43.y Springs 44 are mounted on the rods 42 and engage .stops 45. 'I'he ends of the rods are providedrwith stops 43 which engage the bearings 43 to limit the movement. of the rods42. When the pawl 32 releases the cam 33 these springs 42 suddenly rock the'shaft 40 and this. bymeans of the segmental gears 33 and 33, rocks Ithe shaft 34 so as fto move the cutter arms 31 downwardly to cause the cutter 36 to sever the web 'I3 of the 'I'he movement kJ yoi the, cutter andl associated parts starts thefresetting.` mechanism for the cutter into operationJThisislaccomplished as follows: 'I'he rod 42, see Figs. l5 and 6, is provided with two projections 42a and 42h spaced apart. Between these projections `is locatedv a pivoted a'rm 41a movably mounted on a stationary stud 41b.` :Ihis'arm is arranged so that it will stay in any L"position to which it is moved. Any' means for securingthis result'may be provided. As herein showna series of spring members 41c engage the arm 41a and are pressed against it by a nut 41d which can be tightened to secure the desired frictional contact, see Fig.l '1. The end 41e of this lever engages a switch arm 41l connected with a switch 43 which cooperates with contacts 49 connected in the electric circuit 5I, see Fig. 2. -Whenthe cutter is in its inoperative position this switch is out\of .contact with the contacts as shown in Figs. 2 and 5. When the e cutter shaft 34 is' released and the springs 44 move the arms 42 to throw down the cutter, the projection 42a engages the lever 41 and moves the end 42e vto the left away from the switch arm 41. The spring 53 then moves the switch 48 into contact with the contacts 43, whereupon a circuit is completed in the conductors 5I leading to a suitable electro-magnet device which acts to return the cutter to its linoperative position. Any suitable device for this purpose may be used and I have shown what is termed a thruster unit. more fully shown lin Fig. 4 and whichis now on the market.

'I'he closing of the switch 43 energizes a motor 52 which' rotates a shaft 53, the end of which` projects into afchamber in the cylinder 54 containing suitable liquid and has thereon a wheel 55. 'I'he cylinder 54 is pivotally connected to its support as shown. The rotation of the' wheel 55 moves the liquid through the valve 56 up under the piston 51 and this raises the piston. The piston has connected therewith the rods V53 which are connected by a closing member 53 with a lever pivoted at 3l. I'he connection to the lever 60 is made by means of a pin 62. The ,f lever 60 is pivotally connected to the link 34, which is provided at its end with a slot 35 in which flts a projection 36 on the reset `arm 31 on the shaft 40. When the pawl 32 releases the cam 33 the springs 44 move the cutter rapidly downward and the projection 55 slides up to .the top of the slot 55 before the slower acting reset mechanism has moved the link 64 down' ward. The movement of the piston 51 of the thruster causes the link 64, which is engaging the projection 53 which is now at the upper end of the slot 65, to move the reset arm 31 downwardlyfand rocks the shaft 43'so that the segis automatically reset after its operation.

.arenoso i mentalgears 3l and 33 cause the shaft 4I to be rocked to return the cutter 33 to its initial or inoperative position. This movement of the shaftf moves the rods 42 back to their initial neath the piston Ithrough the baille discharge device 33, thus permitting the weight of the parts to return the piston 51, the lever 33 and the Ilink `ment. The pawl 32 drops down behind the shoulder 32a on the cam 33 just as the switch 43#l is opened, and when this switch is opened the 'shaft 34 and cam 33 move forward until the pawl 32 engages the shoulder 32a, whereupon the parts are held in their reset or retracted position ready for another cycle of operation.

I have shown` a construction wherein thephoto-electric device'for starting the mechanism ed by the hand operated switch, the severing mechanism operates as hereinabove set out and For this purpose I have provided a switch 10 in the circuit 25 leading to the source of supply. This switch, when it engages contacts 1|, connects the photo-electric device in the circuit. When it is moved to engage the contacts 12 it disconnects the photo-electric device from the circuit and connectsY -in circuit the conductors 13 leading u through the contacts 14 and switch 15 to one of the conductors 23 which lead to the pawl releasing electro-magnetic device 23. One oi' the contacts 12 is also connectedvwith the conductors 13 which leads to one `of the conductors 23.

When the switch 10 is moved `to the position Ashown in dotted lines so as to `disconnect the photo-electric device, the photo-electric device is put out' of operation. When the switch is in this position the operator operates the severing mechanism by moving the switch 15 so as to, connect the contacts 14, whereupon the pawl controlling electro-magnetic device 29 is operated to release the pawl 32, causing the severing device to operate.

The use and operation of my invention are as follows: n y

When the expiring roll 3 has about expired, the roll supporting device is rotated so as to move the new roll 4 toward the engaging device 20. In the meantime adhesive has been placed on the web of engaging the new roll, bring it up to the desired speed. When the desired speed has been attained the new roll between the belts 9. The belts 3,

the roll supporting device is further moved so as to w bring the new roll into contact with the web I9 of the expiring roll. The adhesive on the web of the lnew roll then causes its web to adhere to the web I3, and the two webs are moved up into the press and between the source of light 23 and the photoelectric device 22. The double web causes the photo-electric device to act to complete the circuit,

rods 42 causes the switch 43 to be actuated and this completes the circuit through the motor 52 of the thruster unit which acts to then return the parts to their original inoperative position. This operation is repeated each time the web of the new roll is connected to the web of 'theexpiring roll.

When it is desired to start the severing mechal nism by the hand switch, the operator will keep watch on the apparatus and when the web of the new rol'l has been connected to the web of the old roll, he actuates the switch so as to cause-the severing mechanism to be operated to sever the web of the expiring roll. The resetting mechanism automatically acts to reset the apparatus.
